Patent JP-S6441703-A (JP)
Title: Burner
Inventor: NITTA SATORU
IPC: F23D3/10
Filed: 1987-08-05
Abstract: PURPOSE:To prevent malodor from being generated owing to incomplete combustion occurring when combustion is abruptly changed from low combustion over to high combustion by providing a rectangular hole at the upper part of an outer flame incandescent part, providing dense air holes in an inner flame cylinder at a part facing the lower part of the rectangular hole, and forming the upper part of the rectangular hole into a non-hole part. CONSTITUTION:At the time of abrupt changeover of combustion from low combustion to high combustion, a large amount of air is supplied through a rectangular hole 33 having a large opening with respect to a large evaporation amount thereby to reduce the elongation of flame, and at the same time, to prevent malodor due to incomplete combustion from being generated. Further, in a combustion cylinder, dense air holes 34 are formed at parts facing the lower half part of the rectangular hole 33 of an inner flame cylinder 6, and the flame is held positively at these parts to improve the incandescent luminance. Therefore, these parts of the combustion cylinder have good outward appearance which is the same as that of an outer flame cylinder incandescent part 16. When the openings of the dense air holes 34 are too large, air flowing upward from a vent hole 13 of an inner flame cylinder top plate 12 becomes deficient, and incomplete combustion occurs at the upper part. Therefore, the dense air hole 35 is formed into two stages, and the upper part of the stages is formed into a non-hole part.

IPC: F16K31/06
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To drive a valve element in both directions with small power consumption by arranging a tapered spring between a magnetic pole housing a coil and a valve element for pressing the valve element in the opposite direction to the coil, which spring has a diameter at its valve element side smaller than that of the magnetic pole side. SOLUTION: A tapered spring 16 is arranged on a flange 2 through a spacer 12 and a sub-valve seat 15, for pressing a support disc (valve element) 8 and a valve seat 14 against a valve seat 24 of a gas meter. A sub-spring 17 is arranged between the support disc 8a and a head of a pilot pin 10. A plunger 7 is attracted through a fixed iron core 4 by magnetic force in a downward direction of a permanent magnet 18. The downward magnetic force exceeds up-pressing force of the tapered spring 16 applied to the plunger 7 through the spacer 12. That is, attraction of the plunger 7 and the foxed iron core 4 is not cancelled by the up-pressing force of the tapered spring 16.
